SPECIFICATION forming part of Letters Patent No. 484,729, dated October 18, 1892.

Application filed April 13, 1892. Serial No. 429,051. (No model.)

To all whom t may concern.-

Be it known that I, DANIEL BEST, a citizen l of theUnited States, residing at San Leandro,

Alameda county, State of California, have invented an Improvement in Lubricators; and I hereby declare the following to be -a full, clear, and exact description of the same.

My invention relates to a novel device which is especially applicable for lubricating the movable parts of steam or gas engines and for other apparatus in which the action of the lubricator is regulated by the movement of the machinery itself.

It consists in certain details of construction, which will be more fully explained by referencetotheaccompanyingdrawings,inwhich- Figure 1 is a vertical section of my lubrieator as arranged for a steam-engine. shows the same adapted for a gas-engine.

A is a cylinder or chamber adapted to contain the lubricant, having a suitable opening in the top, through which it is supplied, and an opening in the bottom for discharge.

B is a vertical stem, the lower end of which is turned down to iit the discharge-opening O in the bottom, so that when the rod is down the shoulder entirely closes the opening and prevents any escape of the lubricant. Beneath this opening is a chamber D, having a conical closed chamber E projecting from its lower end. In the sides of this pointed chamber are made openingsF for the escape of the lubricant when the chambers D and E shall have become filled, and it iows downward to the exterior point of the chamber E and drops from it into a receptacle G, from which it is conveyed by passage I-I to the point to be lubricated.

I is an arm fulcrumed at one end and passing through a slot in or otherwise engaging the vertical rod B. The free end of this arm projects a short distance beyond the vertical rod B and is engaged by the rotary arm J, which is fixed to a small shaft. passing through the side of the chamber A. This shaft has upon its outer end a pulley or other device by which connection is made with some moving part of the machinery. In the present case a pulley is employed, and a belt or chain band from this pulley passes around a corresponding one upon the engine-shaft. The point of the crank-arm on the inner end of the shaft thus Fig.2'

engages the end of the arm I at each revolution of the shaft, raisesit, and with it the vertical rod B, which drops by gravitation as soon as the arm is released, and closes the opening O. The point of the rod B ills the space of ,the discharge-opening C so nearly that when the rod is lifted but a short distance only a thin film of the lubricant works into the opening, and this is constantly moved downward by the reciprocation of the rod until it finally produces a sufficient quantity to fill the chamber beneath up to the line of the discharge-openings. The gradual accumulation of the lubricant will in time cause it to move by gravitation down to the exterior point of E, from which when it has sufficiently accumulated it will drop off. The rapidity with which this action takes place is regulated by the amount of lift which is given to the vertical rod B. This is regulated by means of a screw-stem K, which is connected with the arm I and draws it back, so that it will be very slightly engaged by the rotating arm J, or presses it forward, so that it may have a more complete engagement, and the rod B will be lifted higher.

Any suitable connection may be made between the arm I and the screw-shaft K. In the present case it is shown as a loose eye or hinge; but the arm I may be made elastic with a rigid connection with K, in which case its elasticity would cause the valve-rod B to close more quickly when released from the arm J.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

- 1. In a lubricator, thecontaining-chamber having a discharge-opening in the bottom, a receiving-chamber beneath said opening and discharge-openings from this chamber, a vertically-moving rod, the lower end of which enters and fills thedischargeopenings of the chamber, an adjustable arm I for regulating the lift of the valve and by which the rod is allowed to remain normally in position to close the opening, and a rotary lever-arm J, moving within the chamber and engaging the arm I, whereby the latter and the rod are raised at each rotation of the arm J, substantially as herein described.

2. A lubricator consisting of a containingchamber having a discharge-,opening in the whereby the amount of engagement and, the bottom,a valve fitting said opening having a corresponding' lift to the valve are regulated, stem extending vertically upward through substantially as hereindescribed. the chamber, a transverse arm I, engaging the In witness whereof I have hereunto set my 5 stem, a horzlnntal shaft passing through the hand.
